It's a strange faith, he never offered anyone anything but his personal assurance this won't happen;
"Most truly I say to YOU, The hour is coming, and it is now, when the dead will hear the voice of the Son of God and those who have given heed will live. 26 For just as the Father has life in himself, so he has granted also to the Son to have life in himself. 27 And he has given him authority to do judging, because Son of man he is. 28 Do not marvel at this, because the hour is coming in which all those in the memorial tombs will hear his voice 29 and come out, those who did good things to a resurrection of life, those who practiced vile things to a resurrection of judgment." Jo5:25

"And the wolf will actually reside for a while with the male lamb, and with the kid the leopard itself will lie down, and the calf and the maned young lion and the well-fed animal all together; and a mere little boy will be leader over them. 7 And the cow and the bear themselves will feed; together their young ones will lie down. And even the lion will eat straw just like the bull. 8 And the sucking child will certainly play upon the hole of the cobra; and upon the light aperture of a poisonous snake will a weaned child actually put his own hand. 9 They will not do any harm or cause any ruin in all my holy mountain; because the earth will certainly be filled with the knowledge of Jehovah as the waters are covering the very sea." Isa11:6
